First, notice that the graph is defined on the interval [0,16} on the x-axis, thus, the domain of the function is the interval [0,16}
To find the range, we can look at the graph and locate where it's defined on the y-axis. On this case, the graph is defined on the interval [0,900}, therefore, the range of the function is the interval [0,900]
Finally, we can see that the y-intercept is where x = 0. As we can see, if x = 0 on the graph, we have that the function is defined on the point (0,900), therefore, the y-intercept is the point (0,900)
